STEERING DEVICE FOR TRACTION-ENGINES.

To all whom it may concern:

.Be it known that I, THOMAS HUGHES CUDDY, 1 of the city of Winnipeg, inthe Province of Manitoba, Canada, have invented certain new and usefulImprovements in Steering Devices for-Traction-Engines, of

which the following is the specification.

The invention relates to a steering device for traction engines and theobject of the invention is to supply an improved means for guiding thefront wheels of a traction engine, the device being particularlyadaptable to those traction engines which have the front wheelsindependently pivotally connected to a stationary front axle.

A further object of the invention is to supply a means which will renderit absolutely impossible for the steering device to turn the frontwheels to which it is con nected more than a set distance therebyavoiding any possibility of damaging the traction engine through toosharp a turn being made. I j

A still further object of the invention is to provide a steering devicewith a pair of forward guide wheels one of which can be adjusted inrespect to the other and a still further object is to provide a steeringdevice which can be controlled from the traction engine when desired.

With the above objects in view the inven-' tion consists essentially inthe arrangement and construction of parts hereinafter moreparticularlydescribed and later pointed out in the appended claims.

Figure 1 is a side view of a traction engine supplied with my steeringdevice, one of the carriage wheels being removed and parts broken awayto expose construction. Fig. 2 is a plan view of the same parts beingbroken away to expose construction.

Fig. 3 is a front view of the steering device.

Fig. i is a plan view of the steering device and front wheels of atraction engine showing the position certain parts have when the frontwheels are turned to the extreme position.

In-the drawings like characters of reference indicate correspondingparts in each figure. 1 represents a traction engine of which 2 is theframe, 3 the platform, 4 an internal combustion engine and 5 the usualcanopy or top which covers over the engine and platform. Theframe iscarried re'arwardly. by the traction wheels 6 and 7 and forwardly ISpecification of Letters iatent.

by the bolster, 8 which is secured permanently to the cross axle 9,which axle has the ends thereof forked in the usual way receivingpivotally stub axles 10 and 11 supplied with carriage wheels 12 and 13.Arms 14 and 15 extend rearwardly from the stub" axles and are connectedby a cross bar 16 in the usual way, this construction being such thatwhen one of the carriage wheels is turned the other is turned a similaramount by the action of the bar. The above parts are of ordinaryconstruction and are simply described to show how my device is applied.1( represents my steering device which is now described in detail.

18 isa more or less V-shaped frameformed from a pair of bars 19 and 20connected together forwardly and having the rear ends supplied withextending plates 21 and 22, the plate 21 being held to the outer end ofthe axle 10 by means of a pin 23 while 22 is fastenedto the inner end oftheaxle 10 "bymeans of a pin 24, the bars 19 and 20 in this way spanningthe axle.

25 is a cross beam formed from a top and bottom bar 26 and 27 spacedapart by a pair of short channel irons 28 and 29. The forward end of theframe 18 is passed between the plates 26 and27 and fastened to the sameby a vertically disposed pin 80.

31 is a brace bar connected permanently to the frame 18 and 32 and 83are brace rods passing between the ends of the brace bar.

and the channel irons '28 and 29. These rods are supplied withturnbuckles 34 so that theycan be adjusted.

The beam 25 carries a number of bolts .35 arranged to the side of thebolt 30 which bolts are supplied so that the beam can be adjusted inrespect to the frame 18. This is done by withdrawing the bolt 30 andfastening the frame to the beam by one or other of the bolts 35. Whenthis is done the turnbuckles 34 will need to be adjustedto line up thebeam with the axle 10. The beam carries at the ends a pair of swiveledaxles 36 and 37 supplied with guide wheels 38 and 39. j

Arms 40 and 41 extend forwardly from the swiveled axles and areconnected by a cross rod 42 supplied with a turnbuckle 13. Although Ihave shown a turnbuckle in this instance it will be understood that anyother suitable adjusting means could be employed to equal advantage.
